Date Nov. 14, 1991.Liquid is enclosed in a resiliently deformable container, the neck of which has a microfiltering membrane which is permeable to the liquid but impermeable to air when wet. Since the container resiliently recovers its shape after it is deformed, the liquid remaining in contact with the outside of the membrane after use is sucked back in and the membrane is kept moist until the next time the container is used.</p> |
